Consequently, in Figure 2, it can clearly be observed that the recorded sea clutter returns occur within a successive range cell region for both the sum and azimuth difference channels. For the elevation difference channel, however, the recorded sea clutter returns occur within two separate range cell regions.
In the monopulse radar system, the angular information of a target is extracted from the monopulse ratio (MR), which is the ratio of the difference channel and the sum channel phasors.
Now, more and more phased array radar (PAR) systems are used on airborne or missile-borne platform, and sometimes, because of the limitations of the platform size, data storage capacity and costs, multiple channels cannot be achieved and the sensor has only two channels--the sum and the difference channel, which is named as monopulse PAR, so in this paper, the forward-looking imaging of monopulse PAR is considered.

The first difference channel produces the desired phase signal, and the second difference channel measures optical alignment and disc wobble.
This is separate from the national Weather Channel, which features local forecasts "on the 8s." The difference Channel 5 brings is that it will feature Channel 5 meteorologists as part of the package.
The monopulse signals from the feed horns are fed to the monopulse-comparator unit, which derives the difference channel offset signals corresponding to azimuth and elevation of the antenna along with the sum channel signals.
One big difference Channel 30 has over the other stations is they have only three commercial breaks inside the newscasts - with the equivalent time to the other stations' four breaks.
The working of a difference channel [network.sup.8] is based on the principle of a hybrid tee junction.
Using insights mined from customers' buying patterns, you can test pricing and markdown optimization in difference channels. Or target product rollouts at specific customer segments.
